ROOFING FINISHING.

SPECIPIGATION forming part of Letters Patent No. 313,852, dated March 17, 1885.

Applit'aion filed July 23, 188

To aZZ 1071,0721 it may concern:

Be it known that I, LEWIS D. CORTRIGI-I'I, a resident of the village of Hyde Park, Illinois, and a citizen of the United States, have invented a new and useful Improvement in Roofing Finishings, of which the following is a specification.

My invention relates more particularly to the finishing of the ridges and valleys ot'roofs, and it has for its object the construction of a ridge or valley that can be painted and finished in sections before it is placed in position, and that permits of an easy and effectual attachment of the roofing material thereto; and it consists in the general arrangement and construction of the material constituting the ridge or valley, as hereinafter described.

The difficulty heretofore experienced has arisen from the fact that a perfectly air-tight and waterproof connection of the roofing material at the ridges and valleys was practi- (-ally impossible. Any loosening of the material by the action of the weather or from the contraction and expansion of the metal,where metal was used, arising from heat or cold would cause leakage and consequent injury to the building. All these objections are obviated by my invention.

In thedrawings. Figure 1 shows a sectional riew of my invention applied to both the ridge and valley of the house. Fig. 2 shows the same when applied to inclined valleys. Fig. 3shows a side view of my invention, and Figs. at and 5 detailed-sectional views.

A indicates the first, B the next, and O the final, fold in the metal, and D the extended strip by which the ridge or valley is nailed to the roof-boards.

In constructing my improved ridge or valley finishing, I take a piece of tin or other sheet metal and bend it along the Iniddlelongitudinally to the proper angle of the particular ridge or valley to which it is intended to be applied. I then fold the sides back beneath the outside portion of the finishing until the center angle is nearly reached. I then again fold the material back upon itself, and preferably, but not invariably, extend it outwardly until it has passed the point at which the first backward fold occurred a convenient distance, where it is trimmed off.

In practice I determine the width that the 'ing the parts by soldering.

(No mode.)

strip of metal should be to make the proper folds, and cut it to such width before anyfolding has taken place. I then place the ridge in position and nail it fast to theroof through that portion which extends beyond the first .backward fold. Everything is now ready to place the roofing material-metal, shingles, slates in position. To do this, I take a. shingle or piece of slate or other material and insert it into the fold made by the first backward turn of the metal composing the ridge, and push it well up into such fold and nail it fast to the roof in the usual manner. and in this way continue to lay the roof until the first row of shingles or slates is laid. The second and subsequent courses are then .laid so as to break joints, and the work proceeded with in the usual manner. In the case of a valley I re verse theridge so that its apex shall be down, and lay my roofing material over the strip as it is nailed to the roof. I extend the material to bring it just over the edge of the fold, so that thewater from either side will fall directly into the valley. If it tlow up underneath the fold, it strikes the turn in the metal and is prevented from escaping from the valley into and through the roofing, so that any leakage along the valley is impossible.

In making a valley I prefer to leave more space between the apex and the final fold than in the ease of a ridge. and so do not carry the metal back so far as in the case of the ridge before making the final turn or fold in the material. And in the attachment of a metal roofing to the valley, I bend the edge of the material so as to hook into or under the final fold of the metal in the valley, and by hammering it down I make a secure and perfect connection without nailing the roofing material through the folds of the valley or fasten- In this way I 0bviate the labor and expense of the soldering or nailing required in making connection to a valley like those in common use.

In practice the ridge or valley may be made in sections of any convenient length and then connected together by sliding the ends of one section well into the end of anotherr This mode of attachment is well adapted to ridges and to valleys which stand at an angle; but in the case of horizonal valleys soldering should be adopted to make a perfectly tight and efficient joint. The manner in which the connections aremade, however, is something that may be left to the judgment of the user, as it .is not in this feature that my invention consists.

The construction and application of my improved ridge or valley will be apparent from an inspection of the drawings without further minute description or details.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. A ridge or valley constructed of metal bent longitudinally at A, B, and O, substantially as described, and for the purpose set forth.

2. A ridge or valley constructed of metal bent longitudinally at A, B, and O, and providedwith strip D, substantially as described, "and for the purpose set forth.

3. Aridge or valley provided with longitudinal laps or bends for the reception of the tudinal laps or bends for the reception of the:

roofing material, whereby such material will cover one portion of the ridge or valley and in turn be covered by another portion of the ridge or valley, substantially as described.

5. A ridge or Valley provided with longitudinal laps or bends for the reception of the roofing material, constructed substantially as described, whereby it is made convertible from one into the other, substantially as described.
